  "textContent": "A redundant power supply circuit with a dual power supply, an electronic device, a system, and a pumping unit. The circuit includes a photovoltaic hybrid unit for energy storage and power generation, a dry battery, a first boost circuit, a second boost circuit, a first diode D and a second diode D. A first controller of the first boost circuit is configured to perform closed-loop control on an output voltage of the first boost circuit based on a first voltage setting value V when the photovoltaic hybrid unit for energy storage and power generation generates power. A second controller of the second boost circuit is configured to perform closed-loop control on an output voltage of the second boost circuit based on a second voltage setting value V when the dry battery generates power. V>V+V, and each of the first and second diodes has a switched-on voltage drop V",
